Is energy storage a single-use transmission asset?
The FERC has previously ruled that energy storage was eligible to serve as a, what we'll call a single-use transmission asset or just targeting one use case.
Is energy storage a generation or supply?
Regulation of the transmission sector prohibits transmission owners to exercise control or any right over any asset which can be considered as generation or supply. Energy storage can be considered as generation when discharging and a load when charging.
Are joint transmission and energy storage Investments a good investment?
However, the value of joint transmission and energy storage investments is much higher than the value of each of them separately. Thus, the Regulator should ensure through incentive regulations or other means that independent transmission investments considers non-transmission assets in order to achieve the most favourable outcome.
How does congestion affect energy storage?
Existing congestion in a power system can positively impact energy arbitrage opportunities and thereby increase the profit of energy storage. Similarly, limited transmission capacity can also increase the need for regulation services and as a result further increase the profit of energy storage.
How is energy storage modeled?
Thermal generation, wind generation, load are limited by upper and lower values (11l)- (11n). Energy storage operation is modeled through energy balance constraints (11k) which keep track of the energy storage state of the charge s ˜ e, t, k, s while taking into account charging d ˜ e, t, k, s and discharging g ˜ e, t, k, s.
Does energy storage add value to social welfare?
The results show that energy storage adds a significant value to social welfare with or without regulation. However, the value of joint transmission and energy storage investments is much higher than the value of each of them separately.
